$375.00 USD
Buyer pays shipping
Sold
Brushless Motor for 40-50%

WB10640 95KV motor in new/tested scratch & dent working condition. This is one of the biggest motors for rc aircraft and should be good on a 35-50lb 3D airplane or 40-50% scale. This is one motor of a few that were poorly packaged when I received them, so they bumped around and caused minor dents and scratches that do not affect performance. I have test run it with a propeller to make sure it works and put Scorpion bearing oil on it. It is meant to run on 14-18s, I can backorder a compatible ESC for it which should make it to your door in 2 weeks (shipped separate from the motor. I will need to know your intended application for the motor and intended source of cooling for the ESC, so I can supply you with the right ESC. You can pay for the ESC separate if you want. The ESC price will range from $200-750 depending on what you need.

Some test data:
140A ESC aerostar(low lift coefficient) 34x12 16s 8000mah 140A 4900rpm 56.5v 8000W
100A ESC tgy 3D 32x10 16s 8000mah ~<120A 5040rpm 58.5v 7020W
160A ESC tgy 3D 32x10 18s 8000mah 125A 5560rpm 64v 8000W
160A ESC: aerostar(low lift coefficient) 34x12 18s 8000mah 150A 5370rpm 63v 9450W

Here's the comparison:

A 100cc gas engine can normally produce up to 10hp at high rpm, and it doesn't take all 10hp to fly 3D.

This electric motor can produce 10.7hp continuously without overheating with good airflow on it, but can withstand up to around 20hp for a few seconds at a time without overheating with time to cool between using such power. Since the motor's maximum power is not always used, there is time to cool the motor between vertical climbs allowing the motor to take the place of a 150-250cc engine, good for a 35-50lb 3D airplane.

What do you mean by mount? I have no standoff extensions, but as long as it sticks out of the cowl far enough it is ready to bolt to the firewall. As for who sells it, I do, I started a motor/ESC business a little while ago, these motors were some in a first order from the manufacturer. As of right now, no one has flown this particular kind of motor, but I have done some tests on it.

I think $375 is a good price already, I'd have to look into shipping though, it could be a bit of a hassle shipping something this heavy to Australia if that's where it is going, hopefully it isn't much.

Do you need an ESC for it, or are you using your own? Not many ESCs go over 14s lipo, if you want good 16s performance I can help.

It weighs 3kg. I am the one who makes the paperwork/manuals, right now I have the specs sheet pictured above. USPS says something like $70 shipping, fedex says over $220, and I can't get a number from DHL which may or may not be cheaper but a lot faster than USPS.

You say this motor SHOULD BE good for a 35 - 50 lb plane , but to me should be leaves a lot up in the air , if you have a plane that says 150 - 170 or 200cc you can then pick which motor depending on how you want to fly . But to me nothing is worse then having a plane that is under powered , I always like more then needed but you don't have to use it .

Sorry, I get in the habit of saying should be as I keep an open mind on things, similar to how I think if I'm correct the Japanese language does not have the ability to express 100% certainty of a future event. I know it has plenty of power for a 35-50lb airplane, I don't know about keeping cool on a 60lb+ airplane being run hard. It takes something like 3500W to hover a 50lb plane, and the motor can handle a continuous 8000W and burst 15,000W. I think a JC super prop 38x14 would be good if you use 14s.


I know what you mean about having lots of power ready to use, I have a slow stick that can go 40mph vertical, but I rarely use that much power. It is way overpowered, but that makes it fun.
